调用公共类：

----------------------------------------------------------------------------
protected void Button2_Click(object sender, EventArgs e)
    {
        string NewsTitle = this.TextBox1.Text;
        string NewsKindName = this.DropDownList1.SelectedItem.Text;
        string NewsBody = this.WebEditor1.Text;
        DateTime PubTime = DateTime.Now;
        string UserName = Session["UserName"].ToString();
        Response.Write(NewsKindName);
        string[] strNewsHtml = new string[] { NewsTitle, NewsKindName, NewsBody, PubTime.ToString(), UserName };
        string[] strOldHtml = new string[] { "@Title", "@NewsKInd", "@NewsBody", "@PubTime", "@UserName" };
        string strFileName = DateTime.Now.ToString("ddhhmmss") + ".html";
        string strFilePath = string.Format("NewsHtml/{0}", strFileName);
        try
        {
            if (WriteFile.createHtml(strNewsHtml, strOldHtml, "mode.htm", strFilePath))
            {
                this.Label1.Text = "生成成功！";
            }
            else
            {
                this.Label1.Text = "生成失败！";
            }

        }

catch
        {
            this.Label1.Text = "生成失败！";
        }
    }protected void Button3_Click(object sender, EventArgs e)
    {
        string[] strNewsHtml=new string[]{"鑫少爷到此一游！"};
        string[] strStartHtml=new string[]{"<!-- start -->"};
        string[] strEndHtml=new string[]{"<!--end-->"};
        if (WriteFile.UpdateHtmlPage(strNewsHtml, strStartHtml, strEndHtml, "NewsHtml/02011139.html"))
        {
            this.Label1.Text="生成首页成功！";
        }
        else
        {
            this.Label1.Text="生成首页失败！";
        }
    }

新建文件夹NewsHtml,生成html文件放在里面

-----------------------------------------------------------

增加一个模板文件

<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
    <title>无标题页</title>
</head>
<body>
    <table border="1" cellpadding="0" cellspacing="0" style="width: 522px; height: 338px">
        <tr>
            <td align="center" colspan="2">
                @Title</td>
        </tr>
        <tr>
            <td align="center" colspan="2">
                发布人：@UserName &nbsp; &nbsp; 发布时间:@PubTime &nbsp; &nbsp;&nbsp; 新闻类别：@NewsKInd</td>
        </tr>
        <tr>
            <td colspan="2">
                @NewsBody</td></tr><tr>
  <td style="WIDTH: 100px">
</td><td style="WIDTH: 100px" >
</td></tr></table></body></html>
